| 中文摘要: |
| 通过负重游泳实验及与疲劳相关生化指标的检测，研究壳寡糖糖基化修饰玉米肽(玉米糖肽)的抗疲劳效应。结果表明：与500 mg/kg玉米肽组相比，玉米糖肽具有更显著的延缓疲劳的效果；与模型组相比，500 mg/kg玉米糖肽剂量组小鼠的负重游泳时间延长92.59%，血清乳酸、血清尿素氮、肝丙二醛含量以及血清乳酸脱氢酶活力分别降低15.67%、13.27%、41.99%和25.53%，肌糖原、肝糖原、谷胱甘肽含量和超氧化物歧化酶活力分别增加54.41%、398.90%、182.76%和94.39%。玉米糖肽可作为天然的抗疲劳功能性食品，市场潜力巨大。 |
| 英文摘要: |
| The anti-fatigue effects of corn peptide glycosylated by chitosan (corn glycopeptide) were evaluated through the weight-loaded swimming test and the detection of biochemical indexes related to fatigue. The results showed that compared with the 500 mg/kg corn peptide group, the corn glycopeptide had more significant effect of delaying fatigue. Compared with the model group, the corn glycopeptide group at 500 mg/kg dose increased the weight loading swimming time by 92.59%, the contents of blood serum lactate, blood serum urea nitrogen, and liver malondialdehyde were reduced by 15.67%, 1327%, 4199% and 25.53%, respectively, and the contents of muscle glycogen, liver glycogen and glutathione and activity of superoxide dismutase increased by 54.41%, 398.90%, 182.76% and 9439%, respectively. Corn glycopeptide has great market potential as anatural anti-fatigue food. |
